Abstract
Bi-Co alloys, ranging in composition from 8.0 to 98.2% bismuth, have been electrodeposited from aqueous solutions containing citrate complexes of the two metals. Co-deposition is of regular type. Cobalt-rich alloy deposits were semibright to bright in appearance. The percentage of bismuth in the deposit decreased when the current density and temperature of electrolysis increased. Stirring increased the current efficiency as well as the percentage of bismuth in the deposit. The presence of ammonium ions in solution improved the current efficiency.
